FIGHT NIGHT AT US OPEN

Novak Djokovic and Philipp Petzschner stopped playing to watch the fisticuffs in the upper deck at Arthur Ashe Stadium (and, boy, would Ashe have hated this). Djokovic, who hails from Serbia, won, by the way, 7-5, 6-3, 7-6 (6).

The off-court action started after a woman appeared to take exception to the continual swearing of a male fan.

"It was far away from the court; we couldn't really see what was going on," Djokovic said. "I hope it was no Serbian up there."
